About Graphing Calculators

Graphing calculators like the TI-84 use mathematical functions to plot curves on a coordinate plane. The basic principle involves evaluating the function y = f(x) for various x-values within a specified range.

Common Functions Supported:

  • Linear: y = mx + b (straight line)
  • Quadratic: y = ax² + bx + c (parabola)
  • Polynomial: y = aₙxⁿ + ... + a₁x + a₀
  • Trigonometric: sin(x), cos(x), tan(x)

Example Calculation:

For y = x² - 4 at x = 3:

y = (3)² - 4
  = 9 - 4
  = 5

Frequently Asked Questions

The calculator evaluates your function at multiple x-values within the specified range, calculates corresponding y-values, and plots these points on a graph using Chart.js.

Graphs are calculated with floating-point precision. Accuracy depends on step size - smaller steps give smoother curves but require more computation.

Basic arithmetic, exponents, parentheses, and common functions: sin, cos, tan, sqrt, log, abs. Use * for multiplication and ^ for exponents.
